After years of experimenting with the mixed technique I have confirmed two things. I love glazing; and too much glaze absolutely kills oil’s refracting light. Thus I have often, even repeatedly, found myself at cross-purposes.

Most of my experiments in the recent years have been attempts to preserve this light. Painting backwards is one of my more notable successes. However, reclaiming the white of the original panel through painting backwards doesn’t really work tactically speaking if the neighboring areas of paint have been worked-up. And adding it back at the finish line (like I did here) is OK but you can’t always guarantee that the surface will accept it by then or that the light so added will be integrated in the way you want it to be. I needed light within the painted surface, a reintroduced light, applied within and over the developing image. And of course it needed to be lean enough to bear a layer or two of glaze. How did the old masters accomplish this? Tempera white.

What is tempera white? Basically, white pigment (I use zinc white but the old masters most probably used lead) ground up in a very lean egg/oil emulsion. The emulsion I use comes from the mixed technique but one could just as easily substitute an egg yolk for the methyl-cellulose glue component. I have used this tempera white before for reintroducing light values within each layer of colored glaze when developing an image chromatically. For examples see: I am curious yellow, Seeing red, and I’d rather be blue. But in all previous attempts, I did not introduce tempera white directly over the egg tempera/imprimatura underpainting, from the get-go, so to speak. That’s what I wanted to do this time, as doing so can free me from any pre-conceived plan of chromatic image development via glazing.

So I’ve been working on a landscape of a farm on the Dammevaart just outside of Bruges. I created a watercolor study of it a few years ago. This functions for the basic composition, color relations and light study.

Based on this watercolor then, I transposed the design to a gessoed panel and worked it up in silverpoint, which tends to be very light valued. I then laid in light areas of color via egg tempera, anticipating the colors to come. Sorry, no picture of this stage is available (but just imagine the watercolor laid in over the silverpoint drawing and you won’t be far off). My interest for the ET level was stating color relations but keeping them as just hints – not fully developed and certainly not saturated. I let the ET fully dry and oxidize for a few weeks before laying in a toned (burnt sienna) imprimatura. Sorry, no image is available of this stage either. The imprimatura acts like a very lean glaze, bringing everything into relation through its hue and tonality. But additionally it also places an inevitable veil over all design elements. The already lightly developed composition got flatter and the ET colors were only slightly visible, as though through a tinted filter.

What to do? White tempera to the rescue. It helped to reintroduce the forms by stating the highlight and quarter tone values. All my seeming tedious homework from the earlier layers played through. My aim now is to complete the painting with just one session of painting into a glaze. The aforementioned homework should allow me to work quickly, spontaneously and yet accurately. And despite all the detail of the under layers, I don’t aim to create a fully detailed realistic painting, rather my goal is a painting that gives the viewer’s imagination space to wander – even if just a little bit. So stay tuned.
